RedTacton is a technology
that bridges the last networking gap, creating the HAN – Human Area Network,
connecting the last meter.It works
by utilizing the electric field on the surface of the human body to transmit
data between a RedTacton receiver and other devices.Data can be transmitted at up to 10 mbps.According to Technology Review, the “transceiver combines an optical
receiver circuit equipped with a super-sensitive photonic electrical field
sensor and a crystal to transmit data.”

Currently, RedTacton is gearing up to compete with Bluetooth,
Zigbee, IrDA (infrared data association), UWB (ultra wide band), and other
wireless communication forms.These
competing technologies are different in that they use radio frequency or light
to transmit data short distances.
They also tend to work at slower speeds that RedTacton which, as mentioned
before, uses the body’s electrical field to transmit at a high speed.
Additionally, since RedTacton requires touch and has a low potential for
interference, it it much more secure than the competition.

NTT, the developer of RedTacton, has recently begun to try and
commercialize the technology.As
reported on Gizmodo (02/25/2008), the technology is currently being marketed as a
way to turn a human into a swipe card.Instead of carrying access cards or wearing a wireless device, people
would wear their RedTacton device and touch the doors or filing cabinets or
other objects which would receive the security clearance from the device.It would be more secure than traditional swipe cards, keys, or wireless
signals.

What does it do?

When using a RedTacton
device, the human body effectively becomes an Ethernet cable, so the body can
use its electrical field to connect devices to networks or the internet.For example, if a person wearing a RedTacton device sat at a table with
RedTacton capabilities that was connected to the Internet, the laptop would
immediately be connected to the internet.While on the surface this seems similar to a wireless network connection,
it is not.There is a physical
connection, the person.Also, the
connection is more secure and does not slow down if many people are using the
same connection, as a wireless connection does.

How is it useful?

Many areas can benefit from
this technology.Initially,
RedTacton could target security, the medical field, and the device communication field.The medical field would
benefit in many ways.For example,
implanted devices could use the technology to transmit information regarding
their performance to doctors, patients wearing the device could quickly and
securely transmit their medical history, and medicine containers could have
chips embedded in them that when touched could send an alarm to the user, if the
user’s device is programmed to know that an allergy to the medicine exists.Device communication is where RedTacton would compete with Bluetooth.Since RedTacton is more secure that Bluetooth, it would excel at
connecting cell phones to headsets and transmitting data from one person’s PDA
to another’s.As mentioned before,
RedTacton is already positioning itself to become a ‘human swipe card’ and
become the ultimate security device. One potential application that will
be explored in depth is gun control.

Why aren't we using it? What are the obstacles?

While RedTacton may be a superior technology, adoption could be slow since
Bluetooth and other radio technologies are already entrenched.Like those products, RedTacton will become more valuable as it is
adopted.If there is nothing for a
person’s RedTacton device to talk to, it is essentially useless.Also, initially, it will be comparatively expensive.
If security applications take off, particularly in the military field, it maybe
years before the technology becomes available to consumers. It
does, however, have to potential to disrupt the Bluetooth market, since it is
more secure and works at much higher speeds.On the medical side, however, it may create a new market.As far as security applications are concerned, it could be disruptive
because it is such a secure way to communicate.Radio swipe cards are much easier to manipulate than a RedTacton human
swipe card.Again, the biggest hurdle
will be convincing consumers that the product is worth the premium that will be
charged because it seems, on the surface, to be so similar to technologies that
are already available.Explaining why it
is more secure and more efficient could be a challenge.Management will need to seriously consider how it will be marketed and
hire excellent marketing people to promote the product. They will also
need to find partners to share in the cost of development. -- More --
